Final answer:
The pressure exerted by 1.7 mol of gas in a 13 L flask at 22 °C is 3.828 kPa.
Step-by-step explanation:
To find the pressure exerted by 1.7 mol of gas in a 13 L flask at 22 °C, we can use the ideal gas law equation: PV = nRT. Here, P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin.
Substituting the given values into the equation, we have:
P(13) = (1.7)(0.0821)(22 + 273.15)
Solving for P, the pressure:
P = (1.7)(0.0821)(295.15) / 13
P = 3.828 kPa
